Thermionic-tunneling multilayer nanostructures for power generation

摘要

A method for power generation based on nanoengineered interface design with partially filled gap is presented. The proposed device allows a substantial temperature difference to exist between heat source and heat sink or two electrodes, thereby maximizing heat source utilization. A unified model and detailed analyses are provided for the solid device operating either as a power generator or as a cooler. Our analyses show that efficiency of about 50% of the corresponding Carnot efficiency can be achieved.
